we are using QXP to impose special security particles, which are is EPS file.
We need to check that each file was imposed well, which was checked in previous versions visually by names
as EPS with no TIFF/Pict preview, QXP shows only GREY rectangle with NAME of file it represents.
Earlier this week we bought QXP2016 and seems that it generates/not generates previews - output is WHITE rectangle with no further details, if it would have NAME and rest is white, than no problem. But like this, big no no.

So the question is, is there possibility to force/switch QXP to act desired way?

Since version 10, the ability to influence preview quality has been canceled. Everything is all about the Xenon Engine, which always tries to make a preview. How great would it be if the user could determine what view he wanted. In Quark, they said the user did not need it. Where is the "greek pictures" option in your preferences?

QuarkXPress 2016 understands EPS (and PDF) natively, so it interprets EPS and shows a preview. It seems that something is different with this specific EPS, as QuarkXPress renders it incorrectly. ...
P.S.: EPS is an outdated file format, please consider using PDF instead.

never thought I'd see this on a Quark Forum

Is Quark now incapable of adding an untouched eps straight into the postscript (either Print, or Export to PDF) ?
If so, which version did this happen?

I have stopped using bitmap EPS in Photoshop - it's too big and in the case of compression it offers only lossy compression that destroys the image. For my customers who require the used images, I have to transfer all EPS images to another format. The TIFF LZW file is much smaller and suits 100% of my customers. Both Quark and InDesign load TIFF images faster (at least on my computer). I stopped using EPS vector because my customers can not open this format. Vector PDF will completely replace EPS. PDF file opens 100% of my customers. I do not know if EPS is outdated, but I know this format is past to me.

No, PostScript is still passed through to a PostScript device to interpret. That includes Acrobat's print driver. Like always, to a non-PS device, gibberish is produced or nothing is depending upon the non-PS print driver. At least the last time I tried it. I think the change was made in 10, but I cannot test right now.

EPS renders fine here and outputs great. And I do prefer it to a PDF as long as the contents do not need color-managed--EPS is not a color-managed format. One reason I prefer EPS to PDF when I desire to use the format is the files are far smaller depending on the contents.

If the contents of individual graphic frames could be hidden, I would like that. Most of my graphics, once placed, don't need to ever be seen again. (Well, and if the preview resolution could be as per v.9 and below, that would be icing on the cake...but Quark would see that as a step or two backwards so I doubt it would ever happen. I would go for simply hiding graphic frame contents on a per-frame basis.)
